The radial centrale is a large bone articulating with the radiale, 
median centrale, and the first three distal carpalia. There are 
five distal carpals, all except the fifth being large bones in 
mutual contact. The fifth isa smailer bone, forming only part 
of the support of the fifth metacarpal. The carpus as a whole is 
remarkable for its thorough ossification and the accuracy of fit of 
its elements,

Niwm.—Neither ilium is quite complete, but the two supple- 
ment one another so as to give a good idea of the whole bone, 
There is no preacetabular projection, the blade of the bone ex- 
tending upwards and backwards from the strong process which 
projects over the acetabulum. The outer surface of the bone 
has a strong ridge running horizontally across it, and the upper 
end shows a faint grooving for muscle-insertion. 
The pubis and ischium cannot be exposed. 
The left femur is only shown in section, but the right gives 
some idea of the form of the bone. It is slender and sigmoidally 
curved. The articular facet at the distal end is well rounded ; 
the upper end of the bone is flattened, but bears a strong 
trochanteric ridge. The tibia and fibula are very slender bones 
shown only in section. The left tarsus is beautifully shown; it 
has the bone preserved and is exposed on its dorsal surface. Its
